To (11 whon z, it may concern. I

it known'that I}; WILLIAM H. KLOOKE, a c tizen of the United States of America, and

a resident of the borough of Brookl n, city of 5 NewYYork, county of Kings, an State of New York, have lnvented certain new and useful Improvements in Clutches, of which the following is a Specification.

The present invention relates generally to Io clutches, and hasfor its main object the pro duction of effectiveand simple means for insuring the. completedisengagement of the clutch members; thereby preventing the clicking .of the clutch-teeth occasioned by r 5 frictional' contact of the parts after their dis-' engagement, and thereby also preventing un-' due wear of the parts.

-In the prior art it has been customary have a latch-moving mechanism operated by a-weight or spring to impart the final motion to entirely free the two members from each other.. 3 It has further been customary to restore the latch-movin -mechanism by the same means that with raws the latch-'that the weight necessary to throw the parts entirelyout is considerable it will -.be under stoodthat it requires considerable pressure to restore .the weight, so much so that 'it is o'onlywith difiiculty, that the operator can brin sufficient pressure to bear upon the,

tree e to effect the proper movement of the gagement, taking the form in the present inparts.

" In the present invention this objectionable feature is avoided by controlling the-latch moving mechanism independently of the means for'withdrawing thelatch so that the power of the operator is not required to restore the parts to their proper position, as 0 was formerly-the case; 4 The means preferred .to carry out this improvement contemplate the utilization'of the power of the machine to lift this weight or re store it to its operating osition, and in the 5- particular form' disclose the driven clutch member is made to do the work.

- Other features of construction and combinations of parts will-appear as the specification proceeds.

-tion has been embodied in a suitable form,

showing also modifications of the same but changes may of course bemade beyond those 7 Specification of Letters Patent.

v 1 indicates a framework of the machine to be operated and throu h which extends the main shaft 2. Mounte loosely on this main shaft is the driving member 3, provided with the clutch teeth 4, on that side which is opposite to the framework. At'its outer end the shaft 2 sup orts the driven-member 5, slidably mounted on the same. This driven member is rovided with clutch-teethfi ad jacent to. t e teeth 4. A key 7 extends through the shaft from a'point between the framework and the driving member and abuts against the clutchesurface of the driven'member. This key rotates with the driven member and is further capable. of a lengthwise movement. -Suitable means are provided.

for norm-ally holding the two members in en stance of a'sprin 8, bearing against the ring 9, which abuts t e driven member, thereby forcing thetwo members together. This spring is h eld in position by'nieans of a cap 10,fastened to the end of the shaft bymeans ofthescrew 11.

lnterposed between the framework and the driving member. is a latch 12 in the form of a pivoted lever, provided with a tapered portion 13. The key is provided with a friction-roll 14, which when the members arein engagement extends into the plane. of the latch, so that when the rotation of theshaft brings the key around to the latch the frie tion roll will travel over the tapered portion andcause the key to move len thwise, thereby opposing the action of the spring and causing thedisenga ement of the members. When the members ave become thusdisengaged, the-rotation of the key ceases. It

In the press 1 ent instance the latch, whichis capable of be-;,

ing withdrawn by swin ing around its pivot when the treadl 15 is epressed, is mounted on the said pivot, so as to be capable of a movement transverse to its pivotal axls- This is readily accomp1 ished by elongating "the hole 16 of the late The latch-moving mechanism, which acts to move the latch in the present instance, takes the form of a pivoted dog 17, which normally has a tendency, by reason of the weight 18, to push the latch into. the position shown in Fig. 2 by en aging In order to relieve t e opfor withdrawing the treadle, it being preferably released and restored by means of the I In'the particular form fol-.

lowed there is a cam, 20,'mounted on the shaft,which rotates with the driven member, .the said cam being provided withanabrupt dropor short lap 21, which comes opposite the friction-roll 22 of the dog 17 substantially at the moment of disengagement of ,the.

members of the clutch. By this means the tapered portion 13 wedges the key still fartherin and causes the com lete disengage ment of the members. Vl en the latch is withdrawn, the spring will cause the mem-' bers to engage again,thereb y rotating the shaft carrying the'oam, which rotation will lift the weight connected to the dog 17 up, so .as to be-ready to drop when the abrupt lap 21 comes around into position to act again.

The ta' ered portion 13 of the latch is preferably a so beveled downwardly, and the friction-roll carried by the key is truncated cone shaped, whereby the sald roll will be kept in proper engagement with the said ortion 13, even though the latch byacci ent should not have assumed its uppermost position when released. v

In order to revent the two members of the clutch to fa l'one ahead of the otherwhen rotating together, there is provided a sp'ringseated s acing member '23, adjacent to one of the teet- 1 of'oneof the clutch members, as shown in" Figs. 3 and 4. .ThlS construction also facilitates the engagement of the driving and driven members with each other, as the spring-seated member will recede when a tooth on the o posed clutch-surface strikes it and will tend to guide the two clutch-surffaces into proper engagement.

In'Fig. 5 is'showna modification in which will spring 25, while the roller 26, which releases and restores the dog by its cooperation with the cam 27, is mounted directly on the latch.

In Fig. 6 the roller 26' is also mounted on the latch; but the dog 28 is o erated by a weight 29 instead of by 'meanso a spring. In both Figs. 5 and 6 a s ring-seated-pin 3O normall tends to assist t e latch-moving dog.

In all three constructions shown the latch preferably be provided .with a cut-out portion 31, which forms a continuation of the tapered portion-13, so that if the s eed of the machine should be too high the. riction-roll carried by the key will not encounter any stop whereby the (parts might be broken- What is claime is 1..
